Patent JP-H06311599-A (JP)
Title: Audio equipment
Inventor: OGAWARA KENICHI
IPC: H04S1/00
Filed: 1993-04-27
Abstract: PURPOSE:To dispense with a power amplifier for low frequency sound by supplying a first electric signal to high frequency and low frequency sound speakers after power-amplifying, and supplying a second electric signal to the high and low frequency sound speakers after phase-inverting and power amplifying. CONSTITUTION:A high frequency sound can be supplied by the first electric signal supplied to a terminal 12 to the positive side of a first speaker 54 via an amplifier 20, a power amplifier 38, and an HPF 50. The second electric signal supplied to a terminal 14, after being phase-inverted by an amplifier 26, is supplied to the negative side of a second speaker 56 via a power amplifier 40 and an HPF 52. On the other hand, a low frequency sound can be supplied by the output signals of the power amplifier 38, 40 to the positive and negative sides of a third speaker 60 via an LPF 58, respectively. Thereby, it is possible to dispense with the power amplification part for the third speaker 60 for low frequency sound which reduces a cost by that portion. Also, sound volume can be adjusted by variable resistors 34, 36. At this time, since the resistor 34 is interlocked with the resistor 36, the sound volume generated from the speakers 54, 56, and 58 can be adjusted simultaneously.

Title: Emergency operation in reactive power compensating converters
Inventor: SAIJIYOU TAKASHIGE
IPC: H02M7/155
Filed: 1977-10-12
Abstract: PURPOSE: To reduce the voltage change in the changeover transient period by setting up a circuit converting only the bridge half section in which a commutation failure occurs into the control at the control angle of a lagging phase, in a forced commutation converter.  
     CONSTITUTION: When a commutation failure detector 14 detects commutation failure, its output signal is transmitted to a changeover control logic 13. It 13 immediately switches a changeover gate 12 into the switching position (b) and stores a thyristor U 2  which does not receive current. The ignition pulse generated from a pulse amplifier 11 is checked by the changeover into the switching position (b). A thyristor W 2  continues applying current (I a). As soon as the control pulse of the control angle +α of a lagging phase corresponding to the thyristor U 2  previously stored at the period (t 2 ) rises, the changeover control logic circuit 13 switches the changeover gate 12 into the switching position (c)

Title: Microwave ion source
Inventor: TORII YASUHIRO
IPC: H05H1/46
Filed: 1987-05-22
Abstract: PURPOSE:To prevent a rise in temperature on a vacuum sealed part of a microwave introduction window by composing this window of a dielectric in lamination structure and providing anisotropic performance of heat conduction for one part of the dielectric in lamination structure. CONSTITUTION:A combination of PBN and BN is used in order to prevent a microwave introduction window 12 from being heated and broken. Namely the introduction window 12 is composed of quartz 12a, alumina 12b, and PBN 12d which is a dielectric having anisotropic performance of heat conduction. Even if charged particles impinge on a surface of the PBN 12d and a temperature of this surface is raised, such composition of this window allows heat of the surface to be rapidly conveyed transversally on the surface, and then the heat is removed through a surface in touch with the metal part by a cooling mechanism 13, so that a rise in temperature can be suppressed. Since heat can be, on the other hand, hardly conveyed longitudinally in the lamination direction of the dielectric, a temperature of the quartz 12a is hard to be raised. Further an O ring 11 for use in vacuum sealing is not broken and so it can be stably operated under high density plasma.
